Within a few short years, scientists developed a consistent theory of the atom that explained its fundamental structure and its interactions. Crucial to the development of the theory was new evidence indicating that light and matter have both wave and particle characteristics at the atomic and subatomic levels. Their petitions have objected to the fact that Bohr had used an ad hoc hybrid off classical Newtonian dynamics for the orbits on some quantum postulates to arrive at the energy levels off the atomic electrons. The new theory ignored the fact that electrons are particles and treated them as waves. By 1926 physicists had developed the law of quantum mechanics, also called wave mechanics, to explain atomic and subatomic phenomena. The duality between the wave and particle nature of light was highlighted by American physicist Arthur Holly Continent and X rays scattering experiment conducted in 1922 Contin sent a beam of X ray through target material on observed that a small part of the beam was deflected off to the sides of various angles. He found that the scattered X ray had longer wavelengths on the original beam. The change could be explained only by assuming that the X ray scattered from the electrons in the target. If the X rays were particles with discrete amounts of energy and momentum, When X rays are scattered, their momentum is partially transferred to the electrons. The recall electron take some energy from an X ray, and as a result, the X ray frequency is shifted. Both the discrete amount ofthe momentum and the frequency shift off the light scattering of completely at variance with classical electromagnetic theory, but they are explained by Einstein's quantum formula.
